Green Building HVAC

Green HVAC Resource

Energy conservation, indoor air quality, and comfort are among the core green building issues encompassed by heating, air-conditioning and ventilation design. These interrelated systems can be complex, expensive to install, and costly to operate but green building also offers many opportunities to simplify and save:

HVAC is more than a few pieces of mechanical equipment. It's a system designed as part of the house. An HVAC system works best when it takes local climate and building designs into account. In a green-built home, heating and cooling equipment can be smaller, less costly, and less complicated.

See Chapter 9 on HVAC in the Green from the Ground Up book for more details or contact us about training .

Designing a System

Central to this premise of thinking small are the many passive solar features built into a green house. HVAC design follows other fundamental building steps that can collectively reduce the size of the heating and cooling system by 30-50%. Solar orientation, insulation, window placement and design, even vegetation on the building site all directly affect heating and cooling loads. Designing a system based on real demand, not conventional practice, is essential.

Makes installation easier and more efficient. Dedicated chases will cut down on labor costs and project complexity.

One or two meetings with the architect or engineer early in the building process.

Systems can often be smaller in green homes with increased insulation saving money

Size HVAC system to meet actual loads using Manual J System is sized appropriately for actual home needs. Reduced heating bills and protects air quality. Careful calculations based on room and home size. The home’s orientation, insulation and window placement affect the heating and cooling load. Manual J is software from ASHRAE Specify high efficiency furnaces and air conditioning units

Research which manufactures sell the highest efficiency units in your area.

Energy Star models furnaces or air-conditioners with a SEER of 14 or higher.

Seal around electrical outlets and all wall penetrations Small penetrations can mean a lot of heat loss over the life of a building. Squirt a small amount of foam to seal each penetration One can of expansion foam. Look for products that use HFC rather than HCFC or CFC as propellants. Size ducts appropriately using Manual D heat loss calculations Ducts are sized appropriately for actual room by room needs. Heat or cooling is efficiently blown to all rooms of the house effectively. Ducts are installed and sized for maximum performance Manual D is software from ASHRAE Seal all ductwork with mastic

Leaky ductwork looses pressure and wastes as much as 20% of conditioned air as it travels.
